In the work of implanting the into the screw hole of the implantable member 7, first, holding the implant bolt 1 by hand and inserting the implanting screw portion 3 into the screw hole of the implantable member 7 and screwing it. However, the fitting between the screw hole of the member 7 to be implanted and the screw portion 3 for implantation is formed so as to become tighter as it is screwed in.
You can screw in only a little with your hand. Therefore, FIG.
As shown in (A), the first nut 5 and the second nut 6 are screwed into the nut thread portion 2 as shown in the drawing, and a wrench or spanner is applied to the first nut 5 and the second nut 6, respectively. The second nut 6 in the screw-in direction and the first nut 5 in the opposite direction by applying a rotational force (torque).
If the nut 5 and the second nut 6 are strongly pressed together, the internal threads of the first nut 5 and the second nut 6 and the nut screw portion 2 of the stud bolt 1 come into strong contact with each other, and A large frictional force is generated between the female threads of the nut 5 and the second nut 6 and the male thread of the nut screw portion 2 of the stud bolt 1 to be in a fixed (locked) state. In this way the nut 5,
After setting 6 in a locked state, a wrench or spanner is applied to the second nut 6 to screw the implant bolt 1 into the screw hole of the implantable member 7 and implant firmly. After implantation, apply a wrench or spanner to each of the first nut 5 and the second nut 6, stop the first nut 5 and turn the second nut 6 in the screw return direction to release the lock and release the nut. Remove 6 and 5. When the stud bolt 1 is pulled out from the screw hole of the member 7 to be implanted, similarly to the above, the first nut 5 and the second nut 6 are attached, and a wrench or a spanner is applied to lock them. Put a wrench or spanner on the nut 5 and turn the stud 1 to remove it.

れている。The shank portion 4 of the stud 1 has an outer surface as shown in a side view in FIG. 1 (A) and a transverse sectional view in FIG. 1 (B), (C) or (D). Plural pairs of planes are formed that are parallel to the axis of the stud 1 and parallel to each other. That is, in FIG. 1B, three pairs of planes are formed to form a hexagonal section with rounded corners, and in FIG. 1C, two pairs of planes are formed to form a quadrilateral section with rounded corners. In D), four pairs of flat surfaces are formed to form an octagonal cross section. Although not shown, only a pair of flat surfaces parallel to the axis and parallel to each other may be formed on the outer surface of the column. The size of each plane formed on the shank portion 4 is
When a wrench or spanner is applied so as to sandwich the parallel planes and a required rotational force is applied to screw in the stud bolt 1, a wide wrench or spanner can transmit the required rotational force to the stud bolt 1. Satoshi In addition,
The upper and lower ends of each plane of the side surface of the shank portion 4 are formed so as to be connected to the nut screw portion 2 or the implantation screw portion 3 with a smooth curved surface so as not to become a weak point in strength. .

Since the outer surface of the shank portion 4 of the stud 1 is formed with a pair or a plurality of pairs of flat surfaces parallel to the axis of the stud 1 and the stud 1 is attached to the member 7 to be implanted. When implanting in the screw hole (see FIG. 2), a wrench or spanner (not shown) is applied to one of the mutually parallel planes of the shank portion 4, and the implant bolt 1 is turned to rotate the implant bolt. Implanting or withdrawing one can be done easily. For example, in the case where three pairs of parallel planes are formed as shown in FIG. 1B, the wrench or spanner may be sequentially changed to the next parallel plane every 60 degrees like a normal nut is rotated. . If the neck of a wrench or spanner has an angle of 30 degrees, it can be replaced every 30 degrees. It may be changed every 90 degrees when the two pairs of parallel planes shown in FIG. 1C are formed, and every 45 degrees when the four pairs of parallel planes shown in FIG. 1D are formed.
